Do you fondly call the whiz kid in your class/ organization ‘Einstein’? If yes, then you aren’t the only one who does so. People around the world honor their friends and acquaintance with the title of ‘Einstein’ for the person’s immaculate brilliance and genius mind. While there may be a lot of genius mind set at work to this date, only once in a century is Albert Einstein born. The 19th century not just witnessed the birth of Albert Einstein, but with it, the birth of modern physics. Rightly known as the Father of Modern Physics, Albert Einstein was, without a doubt, the most influential physicist of the 20th century. With his research and finding, Einstein created a revolution in the field of science. Amongst his numerous works: (a) the general theory of relativity, which provided a unified description of gravity as a geometric property of space and time, and (b) photoelectric effect that established the quantum theory within physics are the most important ones. During his lifetime, Einstein published more than 300 scientific papers, apart from 150 non-scientific works. He was the proud recipient of numerous awards, such as Nobel Prize in Physics, Copley Medal, Matteucci Medal and Max Planck medal. Other than these, he has also been credited by the Times magazine as the Person of the Century. Such was his contribution to mankind that his name Einstein has been made synonymous to being "genius".

Born to Hermann Einstein and Pauline Einstein, in Ulm, in the Kingdom of Wurttemberg, Albert Einstein was one of the two children of the couple. He had a younger sister named Maja Einstein

The family shifted base to Munich, where his father, along with his uncle, founded the Elektrotechnische Fabrik J. Einstein & Cie Company, manufacturing electrical equipment based on direct current.

Albert’s first taste of education was at the Catholic Elementary School, when he was five. After acquiring three years of education, he was transferred to the Luitpold Gymnasium. Post completing advanced primary and secondary school education, he left Germany.

Right from the early childhood, Einstein showed signs of having an in-depth talent and skill for mathematics. During this time, he used to build models and mechanical devices, but those were for mere entertainment.

It was at the age of ten that Einstein’s fantasy for the mathematics grew, when he was handed over popular books on science, mathematical texts and philosophical writings by Max Talmund. These included Immanuel Kant's Critique of Pure Reason, and Euclid's Elements.

In 1894, with the introduction of alternating current to the world, Einstein’s father went out of business. As such, in search of trade, the family moved to Milan initially and a few months later to Pavia.

Einstein, however, stayed back at Munich to complete his studies at Luitpold Gymnasium. Though he did try to adhere to the wishes of his father who wanted Einstein to pursue electrical engineering, it wasn’t long before Einstein withdrew his name from the school roll list as his views clashed with the study regimen of the education center. While Einstein craved for creative learning, the institution focussed on rote learning

Joining his family in Pavia in 1894, he started working on what was his first paper titled, ‘On the Investigation of the State of the Ether in a Magnetic Field’.

The following year, Einstein appeared for the examinations for the Swiss Federal Polytechnic in Zurich. Though he did not clear the test, his grades in physics and mathematics were exceptional.

Adhering to the advice of the Principal of Polytechnic, Einstein enrolled himself in the Aargau Cantonal School in Aarau, Switzerland, for the academic year 1895-96, to complete his secondary schooling.

Fearing the call for military service, Einstein renounced his citizenship in the German Kingdom of Wurttemberg in 1896. His decision was duly supported by his father. In the month of September, he passed the exam with overall good grades, once again gaining top grades in papers of mathematics and physics.

Einstein was only seventeen years of age when he enrolled in the four-year mathematics and physics teaching diploma program at the ETH Zurich. He was awarded the Zurich Polytechnic teaching diploma degree in 1900.

Post graduating, Einstein spent two years in search of a job in the teaching sector, but could not secure even one. Finally, with the help of his former classmate’s father, he bagged the chair of an assistant examiner at the Federal Office for Intellectual Property, the patent office.

It was in 1903 that Einstein became a permanent officer therein. His job involved evaluating patent applications for electromagnetic devices.

His work was mostly related to questions about transmission of electric signals and electrical-mechanical synchronization of time. It was through this that Einstein made his conclusion about the nature of light and the fundamental connection between time and space.

Most of Einstein’s strikingly remarkable works came during this period. He utilized his free time by engaging himself in scientific research. In 1901, he published the paper ‘Folgerungen aus den Kapillaritat Erscheinungen’ (Conclusions from the Capillarity Phenomena) in the most prominent scientific journal, Annalen der Physik.

Four years thence, in 1905, he completed his thesis by presenting a dissertation which was entitled “A New Determination of Molecular Dimensions”. For the same, he was awarded a PhD by the University of Zurich. However, the degree was just the beginning of the many more things that were waiting to come up.

Year 1905, fondly called the Annus Mirabilis or the miracle year in the life of Einstein, saw the birth of Einstein as innovator and creator, for it was during this year that he published his four ground-breaking papers.

The papers provided information on the photoelectric effect, Brownian motion, special relativity, and the equivalence of matter and energy. They not only changed the way the world looked at time, space and matter, but also contributed and laid foundation for the growth of modern physics. Additionally, the papers brought Einstein to the limelight.

As expected, post the publication of the papers, Einstein became instantly famous and was recognized as the leading scientist. In 1908, he was appointed as a lecturer at the University of Bern. However, Einstein quit this position as well as the one he was holding at the patent office to take up the profile of physics docent at the University of Zurich.

In 1911, he became a full-time professor at the Karl-Ferdinand University in Prague.

Three years later, in 1914, he returned to Germany as he was appointed director of the Kaiser Wilhelm Institute for Physics and a professor at the Humboldt University of Berlin, with a special clause in his contract that freed him from most teaching obligations.

Two years thence in 1916, Einstein was appointed as the president of the German Physical Society, a position he held for two years. During this time, Einstein also attained membership of the Prussian Academy of Sciences.

Einstein’s growing reputation resulted in his being invited officially by the Mayor of New York, who personally welcomed the great scientist on April 2, 1921. During his stay at New York, Einstein delivered several lectures at the Columbia and Princeton University.

Post New York, Einstein moved to Washington D.C, where he accompanied several representatives of the National Academy of Science to the White House.

During his journey back to Europe, Einstein made a short stay as the guest of the British statesman and philosopher Viscount Haldane in London. During his visit, Einstein met several scientific, intellectual and political figures and delivered a lecture at Kings College.

The following year, in 1922, Einstein journeyed to Asia and later to Palestine, as a part of the six-month excursion and speaking tour. His travels included Singapore, Ceylon, and Japan, where he gave a series of lecture to more than thousands of Japanese.

His first lecture at Japan lasted for four hours after which he met the emperor and the empress at the Imperial Palace. Einstein visit to Palestine lasted for 12 days. It also became his only visit to the region.

Einstein’s next visit to America was in 1933. He visited several universities during the tour. He even undertook his third two-month visiting professorship at the California Institute of Technology.

While returning to Belgium by the end of March, Einstein heard the news that his cottage and recreational boat had been confiscated by the Nazi’s, who had risen to power under the authority of Germany’s new chancellor.

Upon returning, Einstein almost immediately went to the German consulate where he turned down his passport and renounced his German citizenship. (He had earlier renounced citizenship in the German Kingdom of Wurttemberg.

A new law had been set in Germany according to which Jews could not hold any official positions, including teaching at the universities. Not only were Einstein’s work targeted, he himself was on the list of assassination targets of the Nazi’s with a $5,000 bounty on his head.

Einstein found his temporary shelter in England, before returning to US in the October of 1933. Therein, he took up a position at the Institute for Advanced Study at Princeton, New Jersey, that required his presence for six months each year. His association with the institute lasted until his death.

Einstein was uncertain of his future, as he had offers from the European Universities as well. He, however, made the decision to permanently stay in the United States and thus, applied for citizenship.

In the year 1939, a group of Hungarian scientists attempted to alert Washington of the ongoing atomic bomb research undertaken by the Nazi’s. However, not much heed was paid to their warning. As such, they resorted to Einstein, who wrote a letter to President Franklin D. Roosevelt alerting him of the possibility.

The letter immediately drew the attention of the US government, which became directly involved in uranium research and associated chain reaction research. US utilized its immense financial and scientific resource to initiate the Manhattan Project and surfaced as the only country to successfully develop an atomic bomb during World War II.

Einstein gained a permanent citizenship in US in the year 1940. What was most appealing to him about this country and its culture was the existence of meritocracy unlike Europe. In US, people were rewarded for their works and they had the right to say and think what pleased them.

Einstein, in his later years, was even offered the position of President of Israel, but he declined the same stating that he had neither the aptitude nor the experience.

In 1905, Einstein came up with his revolutionary works, which were focussed on photoelectric effect, Brownian motion, the special theory of relativity and the equivalence of matter and energy.

He worked on thermodynamic fluctuations and statistical physics. He even worked on general relativity and applied the same to explain cosmology. The other work carried out by Einstein include Schrodinger gas model and Einstein refrigerator.

He received the Nobel Prize in Physics in 1921 for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect.

In 1929, Einstein was presented with the Max Planck medal of the German Physical Society in Berlin

In 1936, he was awarded the Franklin Institute's Franklin Medal for his extensive work on relativity and the photo-electric effect

International Union of Pure and Applied Physics named 2005 as the "World Year of Physics" commemorating the 100th anniversary of the publication of the ‘annus mirabilis’ papers.

Albert Einstein has to his name a science park, located on the hill, Telegrafenberg in Potsdam, Germany. The park has a tower by the name, Einstein Tower which is an astrophysical, built to perform checks of Einstein's theory of General Relativity

Washington DC houses the Albert Einstein Memorial. In it is a monumental bronze statue depicting Einstein seated with manuscript papers in hand.

Four months after his death, the chemical element 99 (einsteinium) was named for him
